comb it down or get rid of it.
It looks like an old fashion rug aka wall of hair. Seeing as you are an older gentleman, you should almost always go for hair that resembles your sides and back to a degree, in which you would benefit from a light density hair piece.
the hairline absolutely must be graduated in order to look natural. consult with @Noah
you would also benefit from having a widows peak hairline rather then something rouned or straight across. Could even lower the central forelock down a bit.
